ether, the arylating agent and the catalytic system. In this study, an effective and practical method was successfully developed for the synthesis of acetophenones with high regioselectivity under palladium-catalyzed conditions. A variety of acetophenones was readily prepared from aryl iodides in good to excellent yields under microwave irradiation in a single step. The key feature of our new protocol
烯醇醚的钯介导的芳基化(Heck芳基化)的区域化学对烯醇醚,芳基化剂和催化体系的结构敏感。在这项研究中,成功地开发了一种有效且实用的方法,用于在钯催化的条件下合成具有高区域选择性的苯乙酮。在微波辐射下,一步就可以从芳基碘化物容易地制得各种苯乙酮,收率好至极好。我们新协议的关键特征是使用乙烯基氧基三甲基硅烷作为高度区域选择性酰化试剂。
